• Business Impact Metrics – The tangible business outcomes of your models, such as cost savings, revenue generated, or risk mitigated.

Example scenarios:

• "Walk me through the most challenging aspect of the model you built for your previous employer, and how you overcame it."
• "Explain how you validated your model's performance before putting it into production."

SQL & Data Manipulation

As a Data Scientist, you will need to navigate large, complex databases to find the variables required for your models. SQL skills are tested to ensure you can operate independently without constantly relying on data engineering teams.

Be ready to go over:

• Join Strategies – Knowing when to use inner, left, right, or full outer joins to combine financial tables.
• Aggregation and Filtering – Using GROUP BY, HAVING, and WHERE clauses efficiently.
• Data Quality Assessment – Identifying and handling null values, duplicates, and outliers using SQL.

Example scenarios:

• "How would you write a query to join a customer profile table with a daily transaction table while preserving all customer records, even those without recent transactions?"
• "Explain how you would write a query to find the top 10% of customers based on transaction volume."

Machine Learning Foundations

While the interview is conversational, you must be prepared for hard machine learning questions. The team wants to ensure you understand the underlying mathematics and assumptions of the models you build.

Be ready to go over:

• Supervised vs. Unsupervised Learning – Deep understanding of regression, classification, and clustering algorithms.
• Model Evaluation – Choosing the right metrics (e.g., ROC-AUC, Precision-Recall, F1-Score) for specific business problems.
• Feature Engineering – Techniques for dimensionality reduction, handling categorical variables, and scaling.
• Advanced concepts (less common) – Hyperparameter tuning strategies, ensemble methods (Random Forests, Gradient Boosting), and deep learning architectures.

Example scenarios:

• "How would you design a model to predict loan default, and which evaluation metric would you prioritize?"
• "Explain the difference between bagging and boosting, and give an example of when you would use each."

Financial Domain & Context Awareness

Because you are interviewing at a major bank, showing an understanding of the financial sector is highly advantageous. You do not need to be a finance expert, but you must show interest and basic awareness of how banks operate and use data.

Be ready to go over:

• Banking Terminology – Basic understanding of retail banking, commercial lending, wealth management, and risk divisions.
• Regulatory Considerations – Awareness of model governance, fair lending practices, and explainability in financial models.
• Data Types – Familiarity with financial transaction data, credit histories, and customer demographic data.

Example scenarios:

• "How do you think predictive modeling differs in a highly regulated environment like banking compared to other industries?"
• "What data features do you think would be most predictive when building a credit risk model?"

As a Data Scientist at Regions Bank, your day-to-day work is highly collaborative and dynamic. You will be responsible for translating complex business problems into structured data science projects. This involves working closely with business partners to define objectives, identifying the necessary data sources, and executing the technical modeling pipeline from scratch.

A major component of your role is data extraction and preparation.
